A hypothesis test was made ofH0:1=2versusH1:12.Independent random samples were drawn from approximately normal populations. The sample means were1= 9and2= 11. The sample standard deviations weres1= 3 ands2= 6. The sample sizes weren1= 16 andn2= 12.
a) Find the value of the test statisticst=round to 2 decimal places.
b) Find theP-value =round to 2 decimal places.
c) Interpret theP-value.Do yourejectH0at the= 0.05 level?Enter Yes or No to indicate your interpretation.
Yes, rejectH0at the= 0.05 level.
No,do not rejectH0at the= 0.05 level.
